Yo've got a lot of guts Paul.
A Triumph powered helicopter!

Don't blame it on me. I don't trust Triumph twins at ground level!

Actually, that's a little unfair. Someone I know has clocked up huge milleages on a 1948 Speedtwin.

It's an Adams-Wilson Hobbycopter or Choppy.

The one in the pictures is at the Oregon Air and Space Museum

Yeah, there was a guy giving helicopter rides at a bike event, I went over looked at the copter, it had a evinrude V6 on it.. NOW, I have towed numerous large ski boats back to port.. so.. I didn't ride..

There are some things Even I won't risk.. now a triumph chain driven heli.. Someone hand me a revolver and one shell first.. safer.. Well.. each to his own, considering the way "other selfish" drivers "OWN" the road, flying would be safer, even with a chain drive and lucas ignition.

The evinrude v-6 could be IIRC the first rotorway series.

The choppy...well I doo have a set of plans for it.

Now what I am looking for is more details on the
"bensen flying carpet" and the 2 different models
I have pix of. Propulsion provided by "Briggs and Stratton".

It WAS on the front cover of Popular Mechanics you know...

I think it is used for mass rust prevention. Fly it over a parking lot and it will coat every car there with a fine film of oil.

I was about to say you can find it by following the oilslick.

An Evenrude motor on a helicopter? well pigs can fly then .My record for destroying an Evenrude 225 hp outboard was 41 engine hours !

Yes, the b-12 (I couldn't re-call the "b" number)

But there is a pix of another one, slightly different.
The b-12 looks like 12 rotor's, I think the other one
has 5 rotors, with 2 engines on each hub.

I have a set of original plans for a Choppy, bought them on ebay maybe 5 years ago from an estate wind up. Hey! Where else are you going to get a set of DIY helicopter plans for $20 + P&P.

From memory it uses a Triumph/BSA 650 twin and the drive unit from some variety of shaft drive HD bike to get the drive up to the rotor. The plans tell you how to make the pitch control unit and all the other clever bits, and its all done with a drill press, hack saw and files.

After getting the plans I read up extensively on helicopter theory. So when am I going to build it? NWITFW!

See the link, page 172, it's different, only 8 rotors

Also read about the engine/clutching arrangement.

Sorry gentlemen, I thought it was a post of random pictures as I couldn't find any verbiage about what I was looking at :o

Not likely I'll be flying any choppers I build but I might be looking for a test pilot.

That looks like it was built from two shopping carts and a couple motorcycle engines.

My Grandfather once said there is a fine line between bravery and insanity,the trick is knowing when your about to cross it.
